DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-axial punching device for simultaneously punching a plurality of holes in a thin plate member interposed between holes by fitting a punch into holes formed in a die. The present invention relates to a multi-axial punching apparatus for a thin plate-like member capable of easily changing the interval between dies and between punches.

[0002]

2. Description of the Related Art Conventionally, various punching devices have been used as devices for forming holes of a predetermined shape in thin plate-shaped members such as wiring boards, films and metal foils. In this punching device, a thin plate-like member is interposed between a die and a punch, and the punch is fitted into a hole of the die through the thin plate-like member to form a hole in the member. In such a punching device, in particular, when forming holes having various shapes or sizes such as a round shape, a square shape, and an elliptical shape in one thin plate-like member, the punch and the die do not need to be replaced. There is disclosed a punching device that can easily cope with a change in the punching pattern (Japanese Patent Publication No. 8-398).

FIG. 4 is a perspective view partially showing a conventional punching device. Dies 26a, 26 provided with holes are provided on the upper surface of the lower side end 24b of the plurality of U-shaped support members 24.
b and 26c are fixed.

A hole (not shown) penetrating from the upper surface to the lower surface is provided in the upper side end 24a of the support member 24, and a punch head 25 is fixed on the upper side end 24a. ing. The punch head 25 has a cylinder (not shown) disposed inside with a piston (not shown) facing downward. A punch support (not shown) is fixed to the lower end of the piston, and the punches 27a, 27b, and 27c are supported by the punch support. The punches 27a, 27b and 27c are inserted through holes provided in the upper side end 24a of the support member,
The piston moves up and down toward the dies 26a, 26b and 26c as the piston moves up and down.

[0005] The tips of the punches 27a, 27b and 27c are machined into different shapes according to the required perforation shape, and the dies 26a, 26b and 26c are each formed into a shape corresponding to the corresponding punch. Has holes. For example, the tip of the punch 27a is formed in a circular shape, the tip of the punch 27b is formed in an elliptical shape, and the tip of the punch 27c is formed in a square shape. A plurality of punching units 29 including the support members 24, punches, dies, and the like are arranged and fixed on the base 21.

When a thin plate member is punched by using such a punching device, first, the position of the thin plate member is controlled in accordance with a preset program, and a position where a round hole is to be formed is arranged below the punch 27a. Let it. Then, punch 27
a is lowered, and the punch 27a is fitted into the hole of the die 26a via the thin plate member, thereby forming a round hole in the thin plate member. This operation is repeated to form all the round holes in the thin plate member.

Next, the position where the elliptical hole of the thin plate member is to be formed is arranged below the punch 27b, and the punch 27b is lowered and fitted into the hole of the die 26b. Then, this operation is repeated to form all the elliptical holes in the thin plate member. Similarly, all the square holes in the thin plate member are formed by the punch 27c and the die 26c.

As described above, when the punching device shown in FIG. 4 is used, it is not necessary to change the types and positions of the punch and the die according to the change of the punching pattern. A plurality of holes having various shapes such as a rectangular shape, an elliptical shape, and the like can be efficiently formed.

For example, in the case of manufacturing a wiring board, a plurality of modules may be formed from a thin plate-like member serving as one board. FIG. 5 is a plan view showing the punching positions of the thin plate member when a plurality of modules are formed. As shown in FIG. 5, when a plurality of modules 31 are taken from one sheet-like member 9, the perforation patterns of the holes 31 a in each module 31 are all the same. Therefore,
If the holes of the plurality of modules 31 can be formed at the same time, the perforation process can be facilitated and the time can be shortened.

Therefore, using a punching device shown in FIG.
For example, punches 27a, 27b and 27c and die 2
After exchanging 6a, 26b and 26c with punches and dies of the same shape, the thin plate member 9 is arranged at a desired position,
When a plurality of punches are simultaneously lowered by the piston, holes having the same shape can be formed at predetermined intervals. Then, by repeating the process of moving the position of the thin plate member 9 and piercing it, holes of the same pattern can be simultaneously formed in the plurality of modules 31.

[0011]

However, when the size of the module 31 is changed and the space between adjacent modules is changed, the space between the punches needs to be changed correspondingly, as shown in FIG. When the punching device is used, since the punching unit 29 is fixed to the base 21, it is difficult to change the interval between the units 29. In addition, when the interval between the punching units is adjusted and fixed again, the operation becomes extremely complicated.

As described above, in the conventional drilling device,
When a plurality of holes are formed at the same time, the distance between the holes cannot be adjusted, and the distance between the dies and the distance between the punches cannot be easily adjusted to the change in the distance between the modules. Also, the interval (pitch) between adjacent modules
It is necessary to adjust the intervals between the dies and between the punches every time is changed, so that it has been difficult to maintain the pitch accuracy.

The present invention has been made in view of such a problem, and when a plurality of holes are simultaneously formed in a thin plate member, the interval between the holes can be easily changed.
It is an object of the present invention to provide a thin plate-shaped member multiaxial drilling device capable of drilling holes with high accuracy.

[0014]

According to the present invention, there is provided a multi-axial punching device for a thin plate-like member, wherein a punch is fitted into a hole provided in a die to punch a thin plate-like member interposed between the two. A die plate for fixing a plurality of dies at predetermined intervals, a base for detachably mounting the die plate, a plurality of punch heads for driving a punch up and down, and the plurality of punch heads above the die. A punch plate that is arranged and supported at a predetermined interval, and a support member that detachably attaches the punch plate,
A plurality of holes are simultaneously formed at predetermined intervals in the thin plate member.

In the present invention, a plurality of punch heads are supported at predetermined intervals by a punch plate, and a plurality of dies are fixed at predetermined intervals by a die plate. Therefore, a plurality of holes are simultaneously formed at predetermined intervals in the thin plate member by interposing a thin plate member between the punch and the die, and fitting a plurality of punches into each hole provided in the plurality of dies. Can be formed.

Also, the punch plate can be removed from the support member, and the die plate can be removed from the base. Therefore, when changing the interval between the holes formed in the thin plate member, the punch plate is removed from the support member, and another punch plate capable of supporting the punch head at a desired interval is attached. Similarly, the die plate is removed from the base, and another die plate capable of fixing the die at a desired interval is attached. By doing so, the intervals between the punches and the dies can be easily changed, and as a result, the intervals between the holes simultaneously formed in the thin plate member can be freely set.
